Identification and development of cultural practices for upland rice production systems for savanna soils of Colombia

Creator:: Leal-M, Dario
Abstract:: A great potential for increasing upland rice production exists in the savanna soils of Colombia. These vast areas are currently underutilized. However, they have good soil structure, flat topography, coupled with sufficient and well distributed rainfall, making savanna soils ideal for upland rice cropping system. The major constraints to upland...

Response of grain yield, plant height and kernel weight in three winter wheat crosses (Triticum aestivum, L. em Thell) to different methods of selection

Creator:: Salmeron-Zamora, Jose Juan
Abstract:: This study was undertaken to see if a method of handling segregating populations could be employed which combined the positive attributes of the traditional pedigree and-bulk methods. Derived F₅ lines from the pedigree, bulk, and what is identified as a modified bulk method, were obtained from three winter wheat crosses....

Possible compensations of the components of grain yeild in wheat (Triticum aestivum L.) as influenced by genotype by environment interactions

Creator:: Bedoshvili, David
Abstract:: Despite many investigations genotype by environment interaction remains one of the least understood factors in plant improvement. Understanding genotypic differences responsible for such interactions could assist in making more informed breeding decisions. The components of yield being less complex than grain yield per se may be useful for selection to...

Methods of evaluation, effects of intermating and results of one cycle of S₁ family recurrent selection in barley

Creator:: Mareck, James
Abstract:: The focus of this study was to determine if S₁ family recurrent selection might be successfully used for barley improvement. Objectives were: 1) to identify suitable methods of evaluating grain yield in small plots, 2) to study the effects of intermating on mean values and variances of selected agronomic characters,...

Nature of the inheritance of gluten strength and carotenoid pigment content in winter by spring and durum wheat crosses (Triticum turgidum L. Var. durum)

Creator:: Ammar, Karim
Abstract:: Durum wheat cultivars for North-Eastern Oregon have to be competitive in terms of their yield potential with soft white winter wheat cultivars and meet strict quality requirements of the milling industry. Combining the high yield potential of fall planted durum wheat cultivars which have an acceptable level of winter hardiness...

Production of haploid plants in selected winter wheat genotypes through anther culture and intergeneric crosses with maize

Creator:: Mendoza, Maria Graciela
Abstract:: A higher level of efficiency in the production of doubled-haploids must be achieved if this procedure is to be beneficial in plant improvement. Of equal importance is the development of protocols, which are not genotypic specific and result in progeny that represent a random sample of gametes from the parental...

Genetic variability for kernel hardness in two soft winter wheat (Triticum aestivum L.) cultivators

Creator:: Albahouh, Muhammed S.
Abstract:: To remain competitive in the international marketplace, soft white wheat cultivars grown in the Pacific Northwest must have consistent and predictable flour properties including kernel texture. As a consequence, there is a need to develop wheat cultivars for specific end uses. Wheat cultivars with very soft kernels are used largely...

Feasibility of developing bread wheat cultivars with acceptable protein content for non-traditional areas

Creator:: Lorenzo, Ariel
Abstract:: The objective of this investigation was to evaluate the possibility of developing high yielding wheat cultivars whose flour would result in acceptable loaf volumes for non-traditional bread wheat growing areas. Spring wheat germplasm employed included high protein hexaploid derivatives from Triticum dicoccoides, and selections from Argentina with good bread milling...

Estimates of genetic variability resulting from single, top, and double cross populations in durum wheat (Triticum turgidum L. var. durum)

Creator:: Abdennadher, Mourad
Abstract:: The success of a plant breeding program depends upon the availability of useable genetic diversity. Such diversity may be enhanced depending on the type of hybridization strategy employed. Segregating progenies resulting from F2 populations, a double cross, and a top cross were compared for the amount of useable genetic diversity...
